The provided text excerpts from Voodoo's and Obeahs by Joseph John Williams examine the history and development of Obeah, a form of West African witchcraft and sorcery, and its presence in Jamaica. The author traces Obeah's origins back to the Ashanti people, who brought their unique cultural practices, including Myalism (a tribal religion), to Jamaica during the slave trade. Williams analyzes the interplay between Myalism and Obeah, highlighting how both practiced white magic but Obeah, with its use of poison, became more dominant due to its secrecy and effectiveness in a restrictive slave society. He discusses how Obeah eventually came to be viewed as a form of devil worship, particularly after Myalism attempted to regain its influence following the abolishment of slavery. Finally, Williams provides context by examining the evolving legal and societal landscape of Jamaica, including the legislation enacted to control slave gatherings and address the fears of both slave rebellion and poisoning.
